The invention provides a weaning meat rabbit feedstuff for the mouth-open period as well as a production process thereof. According to the formula, the feedstuff comprises the following components in parts by weight: 28 parts of alfalfa powder (at the national standard level 1), 17 parts of extruded corns, 6 parts of whey powder, 1 part of fish meal, 4.2 parts of fermented soybean meal, 3 parts of extruded soybeans, 15 parts of bran, 4 parts of plasma protein powder, 3.5 parts of white sugar, 15 parts of flour, 0.7 part of calcium hydrophosphate, 0.5 part of calcium formate, 0.5 part of table salt, 0.2 part of lysine, 0.1 part of methionine, 0.2 part of glutamine, 0.1 part of tryptophan and 1 part of additives, totaling 100 parts. According to the formula, processing technological parameters are as follows: the diameter of a sieving piece of a grinder is phi 3.0, the pressure of tempering steam is 0.35MPa, the tempering temperature is 85 DEG C, the tempering time is 90s, the aperture of a pelletizing ring die is phi 2.5 and a ring die compression ratio is 1: 8. The weaning meat rabbit feedstuff for the mouth-open period has the nutrition characteristics of balanced nutrient matching, reasonable amino acid matching, good palatability and high digestibility; according to the formula, the production process is scientific and advanced and the pelletizing effect is excellent, and the feedstuff is capable of effectively increasing the feed intake of weaning rabbits, promoting the development of the intestinal mucosa, optimizing the intestinal environment, reducing the incidence of diarrhea and obviously increasing the weaning individual weight and the survival rate.
